Review on Sutinna Channel Amplifier KTD1047 Transistor by Dale Hing

The kit looks like a poor copy of the MX50 SE 2.0 HiFi Amplifier. But not really, because the circuit does not resemble any of the currently known circuits. The boards are not built the way the transistors are used (in the 5551 example this is an EBC configuration but the board requires ECB). The kit is missing 2 electrolytic capacitors (470uF/16V) and the small heatsink has no insulating mica spacers. I wasted a lot of time debugging both amps but to no avail. Do not buy. This is a waste of time and money!
